CakePHP says my controller doesn't exist, but it actually does

[CrimpJiggler]

I created two tables:

CREATE TABLE `comments` (
`id` int(11) unsigned NOT NULL auto_increment,
`name` varchar(100) default NULL,
`content` text,
`post_id` int(11) default NULL,
PRIMARY KEY (`id`)
);

CREATE TABLE `users` (
`id` int(11) unsigned NOT NULL auto_increment,
`name` varchar(100) default NULL,
`email` varchar(150) default NULL,
`firstname` varchar(60) default NULL,
`lastname` varchar(60) default NULL,
PRIMARY KEY (`id`)
);

then added a model and controller file for each of them.

<?php
class Comment extends AppModel {
	
	var $name = 'Comment';
	public $BelongsTo = 
	array(
		'Solution' => array('className' => 'Solution'),
		'Visitor' => array('className' => 'Visitor')
	);	
}
?>

then added CommentsFolder:

<?php
class CommentsController extends AppController {
	
	var $name = 'Comments';
	var $scaffold;
	
    public $helpers = array('Html', 'Form', 'Session','Text','FieldDisplay','Js'=>array("Jquery"));
    
}

<?php
class Visitor extends AppModel {

	var $name = 'Visitor';
	var $hasMany = array(
		'Solution' => array('className' => 'Solution'),
		'Comment' => array('className' => 'Comment')
	);	
}

?>

<?
class VisitorsController extends AppController {
	
	var $name = 'Visitors';
	var $scaffold;
    public $helpers = array('Html', 'Form', 'Session','Text','FieldDisplay','Js'=>array("Jquery"));
}
?>

The comments page works fine:

 

but on the visitor page it says it can't find the controller:

 

 

 

 

It makes no sense at all. I checked file permissions and all permissions in the Controller folder are identical. I found another thread about this problem and someone told the OP to add pr(App::path("controllers")); to webroot/index.ctp and the person found the problem that way, but in my case they are identical. I've tried changing the URL to lowercase. I can probably just make a new table and rename it to Visitors but I'd prefer to understand whats gone here incase it happens again.

your opemning tag in vistors controller:

<?

<?php
class

also check the filename does not have a typo
